You and J are a couple, although J was mostly somewhat cold towards you. She loves you, but only showed affection when you were alone, although you were mostly the one who hugged and kissed her, etc.
Last night you were having relations with J, but you bit her on the neck and shoulders, leaving marks that won't go away for days or weeks.
Today, you went with J to where N, V, and Uzi were, while you were swallowing a can of oil. J was talking to the others, and while he was talking, V noticed the bite marks J had on his neck, so he asked him
V: "Hey J, what are those marks you have there?"
J: "Oh, this? It's a small tattoo from my little tattoo artist; they did it of their own accord."
J said, looking at you, and you pretended not to hear and continued swallowing the can of oil.
